This application is a continuation-in-part of application S.N. 274,840 filed March 4, 1952, now US. Patent 2,752,368, issued June 26, 1956.

The 3-pregnen-20-one includes those 3-pregnen-20- ones which may incidentally possess other double bonds such as in position 1, 5(6), 9(11) or 16(17), hydroxy and acyloxy groups wherein the acyl group is of a hydrocarbon carboxylic acid containing from one to eight carbon atoms, especially in positions 6, 7, 11a and 11B, 14, 15, 170: and 21 or additional keto groups, whenever feasible, especially in positions 1, 6, 7, 11 or 16.

The 17-oxygenated-3-androstene includes, 17-oxygenated-3-androstenes which may additionally possess double bonds in positions such as 1, 5(6) or 9(11), hydroxy and acyloxy groups, defined as above, in positions 6, 7, 11m and 11B, 14, 15 or 16, or keto groups in positions 1, 6, 7, ll, 15 and 16. The 17-oxygenated steroid has at the 17-position hydroxy, acyloxy, wherein the acyl group is defined as above, or a keto.

3-oxygenated bisnor 20 22) cholene includes those compounds which may additionally possess double bonds in positions 1, 4, 5 (6) or 9(11), hydroxy and acyloxy groups wherein the acyloxy group is defined as above, and keto groups in positions 1, 3, 6, 7, 11, 15, or 16. The 3-position of the oxygenated steroid is substituted by hydroxy, acyloxy, wherein the acyl group is defined as above, or keto.

The process of the instant invention comprises treating a steroid enamine, which may be prepared by reacting a 3-keto steroid or a steroid 22-aldehyde with a secondary amine such as morpholine, pyrrolidine, piperidine, and the like, with an alkylation agent especially an alkyl halide having less than eight carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, pentyl, hexyl or benzyl chloride, bromide or iodide, or with an ester such as dimethyl sulfate or diethyl sulfate, and recovering the thus-obtained quaternaryammonium anti-unsaturated steroid salts.

Other quaternaryammonium steroid salts can be prepared by converting a quaternary ammonium steroid halide, by treatment with an alkali base such as sodium hydroxide, to the corresponding quaternaryammonium base and reacting the thus-obtained quaternaryammonium base with an acid such as nitric, sulfuric, chloric, perchloric, formic, acetic, phosphoric, bromic, iodic, periodic, and the like, to produce the corresponding quaternaryammonium salt.

It is an object of the present invention to provide new quaternary steroidal ammonium salts selected from the group consisting of 3 (N quaternaryammonium) 3- pregnen-ZO-ones, 3 (N quaternaryammonium)-17-oxygnated-3-androstenes and ZZ-(N-quatemaryammonium) 3-oxygenated-bisnor-20(22)-cholene salts. A further object of the invention is the provision of a process for the production of such quaternary steroidal enamine salts. Other objects of the invention will be apparent to those skilled in the art to which the invention pertains.

The compounds of the present invention, 3-(N-quaternaryammonium)-3-pregnen-20-ones, 3-(N-quaternaryammonium)-17-oxygenated 3-antrostenes and 22-(N-quaternaryammonium) -3 oxygenated 20(22) bisnorcholene salts are excellent Wetting agents and have antibacterial activity, especially against Staphylococcus aureus, S. albus, S. haemolyticus, Streptococcus fecalis, Bacillus subtilis, Escherichia coli, Aerobacter aerogenes, Salmonella typhosa, dispar or Schottmuelleri, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, Saccharomyces cerevisiae, and Mycobacterium tuberculosis. For this reason the compounds of the instant invention are suitable for topical use and particularly in the cleaning and sterilizing of surgical instruments or fomites. Additionally, these compounds are intermediates for the preparation of other useful complex compounds.

The compounds of this invention are suitable for electrocardiographic electrode jellies. It has been found that g the use of glycerine and starch in these electrode jellies is superior and cheaper to gum tragacanth in the older jelly preparations. However, starch requires a preservative. The instant quaternaryammonium steroid compounds having antibacterial activity make it unnecessary to use additional bacteriostatic agents. Furthermore, the instant quaternaryammonium steroid compounds simultaneously function as electrolytes and enhance electrical conduction by reason of their wetting action.

The use of abrasives such as pumice ELehning, J. Am. Pharm. Assoc. 9, pages 410-413 (1948)] in the electrocardiographic jellies, ordinarily required to scratch the horny layer of the epidermis and thus achieve better conduction thru the lower epidermis strata, is unnecessary when the instant quaternaryammonium steroids are used. A suitable composition of an electrocardiographic jelly thus prepared comprises:

In carrying out the method of the present invention the selected starting compound, dissolved in a suitable organic solvent, such as benzene, ether, cyclohexene, pentane, hexane, heptane, dioxane, glycol ethers, and others, with ether or benzene being preferred is admixed with an alkylating agent, such as an alkyl halide wherein the alkyl group has less than eight carbon atoms and the halogen atom has an atomic weight between 34 and 130. Instead of using an inert organic solvent the selected enamine compound may be admixed and dissolved in the alkyl halide or alkyl sulfate itself. Suitable alkyl halides are the methyl, ethyl, propyl, isopropyl, butyl, pentyl, hexyhheptyl, octyl, benzyl, allyl and propenyl chloride, bromide andiodide with methyl and ethyl bromide or iodide being preferred. Dialkyl sulfates such as dimethyl and diethyl sulfate, ethyl bromoacetate, benzoyl chloride, benzene sulfonyl chloride, toluenesulfonyl chloride, and the like can also be usedto obtain a quaternary compound from the tertiaryamino compound. The preferred reagents, however, are the bromides and iodides of methyl, ethyl, propyl, and butyl. The temperature of the reaction may be between about zero and about the boiling temperature of the solvent employed, but a temperature between twenty and fifty degrees is preferably used with a range between zero and 100 degrees being suitable.

The reaction time depends on the temperature employed and varies for different reaction runs from half a day to 14 days at room temperature, while at higher temperatures, for example, between 40 to degrees in benzene, a reaction time from about four hours to 24 hours is sufficient. Agitation, while not necessary, increases the rate of reaction and is therefore desirable. The solid compounds are usually isolated by filtration of the reaction mixture. If the product has been prepared by adding a solid enamine to a liquid alkyl halide, addition of a solvent such as ether is usually preferable beforefiltration. The precipitate thus obtained is purified by washing the crystals with. etheror benzene. 'Further purificationis achieved by recrystallization of the precipitate from mixtures of methanol and ethyl acetate or other solvents such as acetone, dioxane, Skellysolve hexanes, chloroform or water.

The following examples are illustrative of the process and products of the present invention, but are not to be construed as limiting.
